7 Claims.

This invention pertains in general to vending machines and in particularto a machine of this type comprising a coin selector, a change maker,and a merchandise magazine.

The coin selector is an improvement over the one described in my earlierpatent application filed August 17, 1929, Serial Number 386,582. Themerchandise magazine is of conventional construction and, therefore,forms no part of the present invention. Insofar as I know the changemaker is new.

During the operation of vending machines equipped with my earlier coinselector the coin chutes were frequently found obstructed by pieces ofpaper, pins, and other miscellaneous articles inserted therein.Therefore, one object of this invention is to provide a vending machinewith means for eliminating all such articles from the coin chute so theywill not interfere with the operation of the machine.

Also, in my original coin selector one of the selecting operations wasperformed by sliding the coins down a chute through a magnetic field. Ihave found that this sliding action reduces the speed of the coins tosuch an extent in some instances that the accuracy of the separation isimpaired. Therefore, another object of this invention is to provide acoin selector with means for passing coins through thisselectingoperation without reducing their speed to a harmful degree.

Another selecting operation was performed by rolling the coins through amagnetic field and then accepting those that emerged at less than acertain speed. I have also found that in some instances such a machinewill acceptspurious coins or slugs having the periphery thereof notchedor otherwise deformed in such a manner that their rolling speed isreduced. Therefore, another object of this invention is to provide acoin selector with means for rejecting coins having a deformedperiphery.

When using a vending machine some persons insert more than one coin inthe machine before operating it, and I have found that the subsequentcoins frequently interfere with its operation. Therefore, another objectof this invention is to provide a vending machine with means forreturning all coins that are inserted in it from the time it hasaccepted one coin until after it has been operated.

In the operation of vending machines it is frequently desirable tohandle merchandise selling at an amount different from that of anystandard U. S. coin. Therefore, another object of this invention is toprovide a vending'machine with means for delivering one or more coins aschange with each article of merchandise.

Other aims, objects, and novel features, will be apparent from thefollowing description in 930. Serial No. 471,445

The present machine is especially adapted to accept twenty-five centpieces and deliver a package of merchandise such as cigarettes and twofive-cent pieces in change. It may be adapted, however, to accept coinsof a different size and value; to deliver merchandise without deliveringchange; or to deliver change without delivering merchandise. The machineas shown is adapted to deliver from one to four coins as change but thisnumber may be increased when the machine is adapted to receive coins ofgreater value, or when it is used for other purposes, such as deliveringchange only.

The price range of articles the presentmachine is adapted to handle isunusually large. For instance, when the machine is adapted to receivetwenty-five cent pieces it may be caused todeliver articles ofmerchandise selling for 592, 10, 15, 20, or 25, by adjusting it todeliver the proper number of five-cent pieces in change. It may also bearranged to deliver articles selling from 21 to 24 by adjusting it todeliver the proper number of one-cent pieces in change. As theadjustments necessary to change the number of coins delivered may beeasily made by the owner of the machine, he may arrange it to delivertwenty-five cent articles for twenty-five cent pieces and then whendesirable run out price sales by arranging the machine to deliver one ormore one-cent pieces as change with each article of merchandisedelivered. The scope of the machine may be greatly enlarged by ma it toreceive and deliver coins 'of other sizes, and by increasng the numberof coin magazines so it will simultaneously deliver coins of two or moredenominations as change.

I In order to simplify the description of the machine embodying thepresent invention and, at the same time, make it more definite, thefollowing terms will be used comprehensively as defined:

The term coin" or coins will be used to designate one or more coinswhich the machine is adapted to receive: In the present case this is U.S. twenty-five cent pieces; it being understood that the presentinvention covers machines adapted to receive any coin, or any metalcheck or token having a special monetary value or magnetic quality, andthat this defined limitation applies only to the specific embodiment ofthe present invention described herein.

The term slug" or slugs will be used to designate one or more genuinecoins for which the machine is not adapted; deformed coins of any sizeor value; foreign coins; metal checks; metal tokens; metalwashers; disksof metal; spurious coins; counterfeit cons; and all other metal articlesin the shape of or resembling coins.

The term trash" will be used to designate miscellaneous articles notresembling coins;-such as pins, disks of paper,.cardboard, celluloid,bakelite, and such like, that are inserted in vending machines.

The preferred form of the invention as shown in the drawings comprises avending machine having a suitable casing 10 and a door 11 closing thefront thereof. Supported within the casing 10 is a merchandise magazine12 of a form well known in the art, and attached to the inside of thedoor 11 are a coin selector, a transacting mechanism, and a compartment13 in which one or more articles of merchand se-may be displayed.

The door 11 is provided with a slot 14: in which coins are inserted forthe purpose of releasing the vending machine so it can be manuallyoperated to vend or dispense an article of merchandise such as thatdisplayed in compartment 13. Before a coin inserted in slot 14 can reachthe releasing mechanism, however, it must pass through the coinselecting mechanism, and the purpose of this mechanism is to allow onlygenuine coins to reach the releas ng mechanism, and to reject and returnall slugs and trash. The mechanism of the coin selector accomplishes itspurpose in the following manner.

When a coin is inserted in slot 14 it enters a vertical con chute 15extending toward the rear of the machine and inclined slightly downwardso the coin rolls into a trash eliminator 16. The trash eliminator has arear wall 17 that arrests the horizontal movement of the coin, and aslot 18 in the bottom thereof through which the coin drops against aninclined vane 19 carried by a horizontal pivot 20.

In addition to its purpose of diverting coins against the vane of thetrash el minator, the vertical wall 17 also absorbs all artificialmomentum imparted to coins when they are inserted in the coin slot 14.This obviates all possibility of a person giving a slug an added momentum or particular motion that might cause it to pass through the coinselector where it would otherwise be eliminated.

The vane 19 of the trash eliminator 16 is carried by the pivot 20 so ithangs in an inclined position between the outlet 18 in the bottom of thetrash eliminator 16 and the entrance 21 in the top of the coin chute 22.The vane 19 has sufficent weight and inertia so that all trash comingout of the outlet 18 and striking its inclined surface will be deflectedinto a trask chute 23 and conveyed to a coin cup 24 on the front of thedoor 11 within reach of a person operating the machine. The vane 19 islight enough, however, so that a coin, or a slug of approximately thesame weight, will deflect it and drop down into the entrance 21 of thecoin chute 22. Some light metallic articles, especially those so thinthat they are liable to lodge in a coin chute and form an obstruction,will also be thrown out by the trash eliminator.

The coin chute 22 is inclined downward so coins roll through it and itis also provided with a curved portion 25 that changes the position ofthe coins so they enter the curve with an edge toward the front of themachine and emerge with a side toward the front of the machine.

Coins leaving the curve 25 of the coin chute 22 next pass over the face26 of a horseshoe magnet 27 forming part of the floor 28 over which thecoins roll. The purpose of the magnet 27 is to eliminate slugs ofparamagnetic material such as iron and its alloys. Such slugs will beattracted by the magnet 2'1 so they roll over the face 26 and down theside 28 into chute 29 leading to the coin cup 24. Coins, on the otherhand, will not be attracted by the magnet 27 so they will roll over itand jump the entrance to chute 29 and also barrier 30 into a verticallydisposed chute 31. The barrier 30 is positioned so coins positively passover it but so slugs, even though they are attracted but a small amountby magnet 27, will strike it and fall back into chute 29.

Coins that jump the barrier 30 into chute 31 drop vertically downwardbetween the inclined pole pieces 32 of magnet 33.

The pole pieces 32 of magnet 33 are positioned close together so thereis just room for coins to pass between them, and they are also set at anangle to the direction of coin travel. Furthermore, they are elongatedso they extend the full width of the coin chute so coins in passingthrough these pole pieces must pass at an angle through an elongated orlinear magnetic field. This magnetic field offers a resistance to coinsand slugs passing therethrough dependent upon the amount and intensityof eddy currents or Faucault currents induced therein. Coins and slugsare affected different amounts in passing through this field, and theretarding action of the field deflects the coins and slugs from theirline of travel according to their composition. A separator 34 is placedin the coin chute below the pole pieces 32, and slightly to one side, socoins, and sings affected by the pole pieces as much or'more than coins,are deflected into chute-35; while slugs affected by the magnetic fieldless than coins pass into chute 36 which leads to the return cup 24.

Such slugs as are deflected more than coins are separated and rejectedby conducting all coins and slugs entering chute 35 into chute 37 thatis inclined so the coins and slugs roll down it through the pole pieces38 of magnet 39. Pole pieces 38 are preferably round and smaller indiameter than the coins, and they are located so one forms part of eachside wall of chute 3'1 so there is just. sufilcient space between theopposing faces of the pole pieces for a coin to pass without danger ofbinding. While there appears to be no critical size, I have securedbetter results by using pole pieces somewhat smaller than the diameterof the coins so the magnetic field of the magnet is concentrated in anarea substantially the diameter of the coins.

In rolling between the pole pieces 38 in the magnetic field of magnet 39coins and slugs will be retarded different amounts according to theircomposition, shape, size, etc. Those retarded less, such as coins, willpass over a separating point 39 located beyond the pole pieces 38substantially in line with the bottom of chute 37, while those retardedmore, such as slugs, will not pass over the separating point 39 but willroll downward into rejection chute 40 that leadsto the return cup 24.

In order to prevent mutilated slugs from being accepted the presentmachine is arranged so slugs having a mutilated periphery, or any otherexpedient tending to reduce their rolling speed, will be rejected.

Down to this point the coin selector is provided with an eliminator fortaking out trash; a magnet for taking out paramagnetic slugs; a magnetfor taking out slugsdeflected less than coins; and a magnet for takingout slugs retarded more than coins. Therefore, any slugs accepted bythis portion of the machine must be of substantially the same dimensionsand metallic composition as coins. This group of slugs includes Canadiantwenty-five cent pieces, French francs, and German marks. As Canadiantwenty-five cent pieces are of substantially the same value as the coinsfor which the machine is adapted, it is arranged to accept them, butfrancs and marks are rejected by a coin selecting device incorporatedwith the releasing mechanism.

Francs and marks are similar to coins but they are slightly smaller indiameter, and this difference in size is great enough so they may bepositively separated by it. This separation is eflected by a pair ofpins 43 carried by a release lever 42. Coins coming down chute 41 areconducted to these pins, which are spaced apart so coins will be held bythem but so francs and marks will pass between them and then downrejection chute 44 to the return cup 24. Coins held by these pins effectthe release of the machine in a manner to be described later.

Sometimes there are inserted two or more coins in the coin slot beforeoperating the machine to eifect a delivery. It has been the practiceheretofore to provide vending machines with some means for storing suchcoins until the machine was operated, but such devices areunsatisfactory because, even under the best of conditions, two coinswill frequently become wedged in the coin chute 'side by side and forman obstruction. Therefore, I obviate all possibility of the presentmachine becoming clogged in such a manner by providing it with means forreturning subsequent coins instead of storing them.

This means comprises an interference lever 45 having a hub 46 carriedbetween a stationary pivot 47 and an adjustable pivot 48 (Figs. 5 and6). The lower end of this lever has an inclined face 49 in the coin pathso a coin entering the release mechanism will strike it and move thelever to interference position and hold it there as long as a coin isresting on pins 43 or release lever 42. When in interference positionthe upper end 50 of lever 45 forms an obstruction in the lower end ofcoin chute 37 so coins that would ordinarily enter chute 41 and beconducted to the releasing mechanism are deflected into chute 40 andconducted to the coin return cup 24. A spring 51 carried by the vendingmachine frame presses against the upper end of lever 45 and moves itback to normal position when the machine is operated and the releasingcoin is ejected from the releasing mechanism.

The operating or transacting mechanism that is released by an acceptedcoin and manually actuated to effect the delivery of an article ofmerchandise comprises a shaft 51 journaled in a bearing boss 52 thatforms part of the door 11. Rigidly attached to shaft 51 in front of door11 is a manually operable handle 53, and rigidly attached to the sameshaft at the rear of door 11 are a disk 54 having one or more pins orsprews 55 projecting from the back face thereof for operating the changemaker; and a gear 56 having a function that will be'fdescribed later.

The merchandise magazine 12 is driven by-s'haft 51, and in order tomaintain the transacting mechanism and the .merchandise magazine intheir proper relative position and, at the same time, permit the door 11to be opened, a'sep arable joint is provided comprising a driving member57 rigidlyatt ached to shaft 51 and having two pins projecting from theback face thereof at opposite sides of shaft 51, and a driven member 59carried by shaft 60 of the merchandising magazine and having tworeceptacles 61 on the front face thereof, in which pins 58 arerespectively positioned when door 11 is in closedposition but from whichthey are withdrawn when the door is opened.

The merchandise magazine comprises a plurality of merchandisereceptacles 62 carried by an endless chain 63 that runs over suitablesprocket wheels 64 and 65 respectively supported by shafts 66 and 67that are in turn carried by the vending machine casing 10. Themerchandise magazine is driven by a chain 68 running over a sprocketwheel 69 carried by shaft 66, and sprocket wheel 70 carried by crossshaft 71 that is driven by shaft 60 through a pair of bevel gears 72.

The transacting mechanism also comprises a shaft 73 carried by door 11and having the following parts rigidly joined and rotatable thereon: amovement stop 74 having two faces 75 that alternately come in contactwith a detent '76 depending from release lever 42; a ratchet wheel 77that coacts with pawl 78 carried by stud '79 and held in contact withwheel 77 by spring 80 so the transacting mechanism can not be moved inreverse direction; and a gear 81 twice the size of gear 56, with whichit is enmeshed, so it makes but half a revolution while handle 53, andthe mechanism movable therewith, makes a complete revolution.

Release lever 42 is carried by stud 81' so it is free to rotate withinthe limits of its travel. Its weight, and that of other parts attachedthereto, is distributed so that normally detent 76 lies in the path ofone of the stop faces 75 thereby preventing the transacting mechanismfrom being actuated, but so a coin that has come to rest between pins 43will raise detent 76 above the path of either of the faces '75 therebyreleasing the transacting mechanism so it may be manually actuatedthrough its cycle of movement to effect the delivery of an article ofmerchandise. During this cycle the coin must be ejected from betweenpins 43, and the release arm 42 must be positively restored to stopposition to eliminate all possibility of the transacting mechanism beingactuated through a second cycle until it has again been released byanother coin.

A coin that has released the transacting mechanism is ejected frombetween pins 43, and release lever 42 is restored to stop position, byrestoring arm 82 rigidly attached to release arm 42 and moved by alaterally projecting pin 83 lying in cam slot 84 cutin the front face ofstop disk 74; and an ejector arm 85 carried by stud 86 and having anejector pin 87 projecting laterally from the lower end thereof, and anoperating face 88 near supporting stud 86 that coacts with pin 89carried by release lever 42. Ejector arm 85 is held in normal positionby a retractile spring 90.

A transacting movement of the vending machine rotates stop disk 74 onlyhalf a revolution, consequently, cam slot 84 in the face thereof isdouble so its cycle of movement is twice repeated during a revolution.Each half of the cam slot 84 has an ejector face 91, that moves releaselever 42 in release direction beyond release position to eject thereleasing coin from pins 43, and a restoring face 92 that positivelymoves release lever 42 from ejecting position back through releaseposition to stop position.

For the purpose of checking the operation of the vending machine bykeeping a record of the number of times it has been actuated, a counter93 of well known form is attached to the inside of the door 11 bysuitable means such as screws 94 so it is operated by pins 95 carried bygear 81 through a push rod 96 carried by bracket 97 attached to door 11by screws 98. The operating pins 95 are located at opposite sides ofgear 81 so each time the vending machine is operated one of the pins 95will depress the rod 96 and advance the counter. When push rod 96 is notin contact with one of the pins 95 it is restored to normal position bya spring incorporated in the counter 93.

The change maker comprises a bracket or support 99, attached to theinside of the door 11 by screws 100, having a vertical receptacle 101supporting a removable coin magazine 102, and a horizontal guideway 103carrying a reciprocable slide 104 for pushing coins out of magazine 102one at a time. This slide 104 has a depending projection 105 carrying ahorizontal pin 106 positioned in slot 107 in the upper end of arm 108loosely carried on stud 109. Arm 110, also loosely carried by stud 109,has a lower end 111 lying in the path of pins 55, and an upper end 112carrying laterally projecting pins 113 ad 114. Retractile spring 115 iscarried under tension in a partially extended condition between pin 113,carried by arm 110, and pin 116 carried by a stationary part of themechanism. Pin 114 rests against face 117 of arm 108 and also carriesone end of spring 118 having the other end thereof carried by pin 119 inturn carried by arm 108. Spring 118 is carried under tension in apartially extended condition so pin 114 is normally held in contact withface 117 of arm 108. Coin chute 120 is carried by the mechanism of thevending machine in such a position that coins ejected from the coinmagazine 102 will be conveyed to the coin return cup 24.

In operating the vending machine a coin is inserted in coin slot 14where it rolls back and enters the trash eliminator. In passing throughthe trash eliminator it drops downward striking the inclined vane 19,which it deflects, and then passes on down into the coin chute 22. Thischute changes its direction of movement so it travels parallel to theface of door 11 in a downwardly inclined direction over magnet 27 andthe entrance to chute 29 to chute 31 where it drops downward throughpole pieces 32 and the magnetic field of magnet 33 which deflects itinto coin chute 35. In this chute it is rolled in a downwardly inclineddirection through pole pieces 38 of magnet 39, over the entrance tochute 40, and into chute 41 which conveys it to the release lever 42where it comes to rest between pins 43.

Other articles inserted in coin slot 14 are taken from the chute throughwhich coins travel and returned to coin cup 24 where they may bereclaimed. Trash is eliminated by the angular vane 19 of the trasheliminator 16 and deflected into chute 23.

Paramagnetic slugs are attracted by magnet 27 and caused to enter chute29. Non-magnetic slugs deflected by the magnetic field of magnet 33 lessthan coins enter coin chute 36. Nonmagnetic slugs whose movement isretarded by the magnetic field of magnet 39 more than coins enter chute40. Slugs smaller in diameter than coins but of similar metalliccomposition pass between pins 43 and enter chute 44. Chutes 23, 29, 36,40, and 44, all lead to coin return cup 24.

When a coin comes to rest between pins 43 its weight moves the releaselever 42 into release position in which detent 76 is raised out of thepath of stop faces 75 of movement stop 74 so the transacting mechanismcan be manually operated. This transacting operation is effected by thevendee who grasps the handle 53 and rotates it one complete revolution.This operation advances the merchandise magazine so the next merchandisereceptacle 62 is brought opposite merchandise delivery opening 121 wherethe merchandise in receptacle 62 may be grasped and removed by thevendee.

This transacting movement also operates the change maker. As thetransacting movement is operated each of the pins 55 makes a completerevolution and strikes the lower end 111 of lever 110 thereby moving it,together with arm 108 and slide 104, so the slide ejects a coin fromcoin magazine 102 into coin chute 120. After each of the pins 55 havepassed the lever 110 the parts are restored to normal position by spring115.

The purpose of spring 118 is to allow the transacting mechanism to beoperated in case the change maker should become obstructed by a deformedor misplaced coin. In such a case arm 110 will be moved as usual butinstead of moving arm 108 and slide 104 it will elongate spring 118which is strong enough to normally drive the slide but will stretch whenthe slide is obstructed.

During the operation of the transacting mechanism the parts mounted onshaft 73 make but half a revolution. Therefore, one of the pins 95depresses rod 96 and advances the counter 93 one position. Also, duringthis operating movement, cam face 91 of 0am slot 84 strikes pin 83carried by arm 82 and depresses the end of release lever 42 carryingpins 43 considerably below release position. At the same time, pin 89carried by the release arm 42 strikes face 88 of lever 85 and raises itslower end so pin 87 carried thereby strikes the under side of the coinresting between pins 43 and ejects the coin from between the pins so itfalls down coin chute 122 which conveys it to coin receptacle 123 withinthe vending machine. After the coin has been ejected from pins 43 of therelease lever, cam face 92 of the cam slot 84 moves the release lever'42back to stop position where the detent 76strikes stop face 75 as themovement is continued and prevents further movement of the transactingmechanism until it is again released by-another coin. As the releaselever is moved to stop position by the cam, coin ejecting arm 85 isrestored to normal position by spring 90. When in stop position there issufficient room in the cam slot so the release lever can move to releaseposition before pin 83 of ejector arm 82 strikes the wallof the camslot. Therefore, when the cam slot 84 is in stop position the releasearm 42 is free to move between stop and release position. Then, during atransaction movement, the cam slot moves the release lever first, toejection position, and then back to stop position where it is releasedso it is again free to move to release position under the influence of areleasing com.

When the last merchandise receptacle 62 containing merchandise is movedopposite the delivery opening 121, a pin 124 carried by one of themerchandise receptacles moves an arm 125 on a pivot 126, suitablycarried by a stationary portion of the mechanism, so the word, empty, orother suitable inscription, appearing on target 12''! is visible throughopening 128 from the front of the vending machine. During its movementto empty position, an inclined face 129 moves pin 130 across coin slot14 thereby preventing a coin from being inserted in the vending machinewhile it is empty. A suitable spring, not shown, restores pin 130 tonormal position when the merchandise magazine is filled with merchandiseand moved back to start position. The target and its supporting leverare moved back to normal by gravity.

It is understood that the vending machine embraced by the presentinvention is not limited to the particular embodiment shown anddescribed, but covers such a machine adapted to receive any suitablecoin and deliver any suitable article of merchandise and an appropriateamount of change. The general appearance of the machine and the form andarrangement of its component parts may be altered, and equivalentmaterials as well as means for effecting the various results may besubstituted without departing from the range of the invention.
